With its weatherproof enclosure, the System 920 provides intercom and radio access to firefighters at the turntable and in the basket of an aerial. The system uses only three or four aerial collector ring conductors.
- Comprised of a master station (MS-920), an aerial station (AS-920) and interconnecting cables, the System 920 can be used as a stand alone intercom and radio system for an aerial turntable and basket, or as part of a complete System 900E for the entire aerial apparatus (in cab as well as aerial positions).
- When used with a System 900E, the System 920 allows six radio transmit positions to be occupied simultaneously: one at the driver's seat, officer's seat, turntable and pump panel, as well as two in the aerial basket.
- Turntable and aerial positions connect to the System 900E master station using no more than three collector ring conductors.
- When a crewmember presses his push-to-talk button, only his voice transmits over the radio. Intercom communication between the turntable and aerial positions remains active.
- Repairable parts decrease the lifetime cost of ownership, and fast repair turnaround decreases downtime.
- Interconnect cables are terminated with watertight, quarter-turn twist-lock connectors with gold-plated contacts and O-ring seals, eliminating any soldering required to install or replace components.
- Interconnect cables incorporate a shield on the microphone line and on the overall cable to prevent RF and EM interference.
